.SH NAME
attropen \- open a file
.SH SYNOPSIS
.LP
.nf
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

\fBint\fR \fBattropen\fR(\fBconst char *\fR\fIpath\fR, \fBconst char *\fR\fIattrpath\fR, \fBint\fR \fIoflag\fR,
     \fB/* mode_t\fR \fImode\fR */...);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBattropen()\fR function is similar to the \fBopen\fR(2) function except
that it takes a second path argument, \fIattrpath\fR, that identifies an
extended attribute file associated with the first \fIpath\fR argument. This
function returns a file descriptor for the extended attribute rather than the
file named by the initial argument.
.sp
.LP
The \fBO_XATTR\fR flag is set by default for \fBattropen()\fR and the
\fIattrpath\fR argument is always interpreted as a reference to an extended
attribute. Extended attributes must be referenced with a relative path;
providing an absolute path results in a normal file reference.
